There is integration, analysis, certification, interfaces, etc that are unique to each vehicleWell, as Old Atlas said, at least the new Centaur configuration test would be beneficial, since both systems will require this same test. I'm sure there are other overlapping tests, certifications, etc. that will be of mutual benefit.

ULA is a sub in both instances. Boeing and SNC each have to take that into account but it does not mean Boeing is burdened with the costs for SNC

But the public milestones are significant information. You can pretend if you want that SNC has optional milestones that will put them at parity with SpaceX or Boeing (assuming all complete their milestones on schedule) - but then *you* are the one making assumptions about information "no one really" has.I never implied any of that. Go back and look at your post. You are suggesting Boeing and SpaceX have it in the bag. The reasons you state are not valid and a lot can happen leading to multiple conclusions

Boeing and SNC each have to take that into account but it does not mean Boeing is burdened with the costs for SNCThe difference is that Boeing gets money for the ULA completed milestones from NASA so its not Boeing that is paying but NASA. So the common ULA items is fully paid for under Boeing. If SNC was fully funded I expect that SNC would have had these Atlas V milestones and Boeing would not.

Correct?I am not sure that's the right way of seing it. SNC has as much chances of winning a commercial crew services contract in 2014 (or later) as Boeing and SpaceX at this point. They will receive half of the funding but they should not be seen either as a backup or a junior partner. Not really. Their only realistic chance for SNC after the current CCiCAP is if Boeing and/or SpaceX pull out or are significantly delayed. Because if both of them complete their milestones, they will be quite a bit ahead of Dreamchaser - and the pick for final commercial crew contract will be between Boeing and SpaceX. Or both, if NASA can keep two providers - but I see no scenario where three providers get contracts.So in practice SNC's Dreamchaser is a risk-reduction backup, unless some significant advantage DC has over the capsules comes to light. That's the way it looks to me, at least. I suppose it also depends on how strong the "Shuttle-hugger" force is at NASA too.

Thanks Robert and FF. And yes, Mr Sirangelo noted commercial customers outside of NASA on a very open telecon this evening. Got a lot to write up.

No orbiter was lost to TPS damage from 2 weeks max? exposure sustained in space. Are there ""cheap"" ways to shield the DC TPS so that it can qualify without caveat for this role?The X-37 stayed up for 15 months and the TPS performed fine as far as we know...Since X-37 is a free-flyer, it can fly in attitudes that minimize exposure to MMOD. DC won't have control over its attitude once docked to ISS.

Quote from: PeterAlt on 08/03/2012 11:04 pmAlso, let's not forget that the money Boeing puts into human rating the Atlas V, will benefit SNC as well, since both use the same LV.The item that most interested me for Atlas V was the dual engine Centaur test. I looked up the flight history and Atlas V has never flown a dual engined Centaur. It seems to be something that LM/ULA skipped on spending because of low likelyhood of being used in the original Atlas V development.
Any idea how NASA will number the flights? Will it be a generic label for all commercial providers (ie CTS-1, CTS-2, etc.) or special labels per provider (ie SPX-1, BOE-1, SNC-1)?

More than happy with the awards. They picked the three with the best chance of getting to the ISS soon. I do really hope ATK continues their efforts, as we can never have enough options to service the ISS.

A lot of exciting stuff in the coming years, not just CCiCap development, but the CRS flights from SpX and Orb. I am also really looking forward to the Pad Abort Test and the In-flight abort tests from SpaceX. That is going to be quite a show!
